Where can I find the April firmware?
Have you tried to flash it with s9_fix_upgrade.tar.gz first before you flash it with other firmware? It might solve the issue.
But if it doesn't work you can try the april firmware just found it from here https://bitcointalk.org/index.php?topic=3474618.msg36124081#msg36124081
it's exactly the same problem as with my T9 +, see my subject;)
In your case, I am 99.9% sure that with the PicKit3 you bring back to life your card!
1: extract the HEX file from a functioning card
2: the reinjected into the card that does not work (FW 0X00)
Ps : the PicKit3, the cost is ~_ 25USD

I agree with this I found his thread from here https://bitcointalk.org/index.php?topic=5032987.0 flashing the hashboard with working hex file might solve the issue.
